Specification of Letters Patent.

- Application filed February 13, 1908. Serial No. 415,676.

Patented July 21, 1908.-

To all whom it may concern: 4 v I Be it known that we, MILTON N. GRANT, a c1t1zen of the United States, residing at C0- lumbus, and CARLTON GRANT and ALEX. H. GRANT, citizens of the United States,.re-

i may be roughened or corrugated; to so construct our improved corrugating device as to admit of the shap production of bIlGk of different outlines and at the same time roughen or corrugate the exposed faces of thebrick. These objects we accomplish in the. manner illustrated in the accompanying drawing,in which:-

- from the brick machine showing our 1m-' i as Is indicated at 3 is forced from the brick Figure l is a perspective view .of the deliv v ery end of a buck making machine, showing our improved corrugating and shaping device of the corrugating and shaping device shown in Fig. 1, Fig. 3 is a longitudinal section of a portion of the clay body which isdischarged proved corrugating and shaping device in section therein, Fig. 4 1s a view 1n elevation of a modified form of corrugating and cutting device, Fig. 5 is a 'view in perspective of a brick sha ed and corrugated b the device shown in ig. 2, Fig. 6 isa simi ar view of a different form of brick such as that which may be produced by the employ ent of the construction shown in Fig. 4, an Fig. 7 is.

a view similar to that shown in Fig. 3 showing a modification in the manner of forming the shaping and corrugating bar.

Similar numerals refer to similar parts throughout theiseveral views.

1 represents the discharging head of a known form of brick making machine and 2 the'oblong die which is connected with the head and through which a body of clay-such making machine in' the usual manner on toa longer ed die of a brick machine ing oftheclaybody for the bod such as is indicated at 6 in in use thereon, Fig. 2 is a view in perspective rated into bricks. j v 4 represents one form of. our'atta-chment whichv consists of a bar which is secured to the framework 1 of the brick machine in such manner that said bar passes in front of the upper portion of the mouth of the die. In constructing the bar, one: of the es thereof which is nearest the, die, is bevele or sharpened as indicated at; 45, while on the underside of the bar is provided a longitudinal bead or projection 5 which as cutting table, where saidclay' body is by wires or other suitablecutting devices, sepaindicated in Fig. 3, may be in the'nature of a rod uitably secured to the bar 4 or asindi cated in Fig. 7 of the drawing, may be in the nature of a. short downwardly projecting] .fiange 5 As the oblong body the mouth. of the die, the upper portion of the clay body comes into comparatively thin'layer of clayfrom said 7. 'As a further result of forc' g the clay outward-and its contact with the pro'ection 5 or 5 of the member 4, a fportion oft e clay forming the new surface 0 the body is alternately compressed in front of said projection of clay is forced from contact with .the bev-, ele'd edge of thebar 4;, resulting in strip $5 Figs. 3 and 1 and then forced beneath the latter and'per-- mitted to rise in rear thereof, this successive operation resulting 1n the production of transverse corrugations or depressions and mtervening'ridges on the surface of the clay bod When said clay .body is 'cut into bric s, itv is. obvious thatthe surface thereof which has been acted upon, as described, by

said projection 5, will present a roughened or substantially corrugated appearance.

In case it is desired to roughen or corruate not only the u per surface of the brick, but one side thereo at right angles with said surface, it is obvious that the bar 4 may be provided with a right angle bend which is ollowedb the projection 5 and that such downwardl y bent portion will serve to'simi larly shave the surface'from the side of the.

cIaIy body and roughen said surface. n Fig. 4 of the form of bar which includes a downwardly bent end portion for operation on the-side of .100 rawing, we have shown a the'brick, said downwardly bent f portion being shown concaved at 4 and said concaved portion having'a vertical termination 4." By the employment of a bar of this kind, it will be understoodthat the clay body 3, will not only be formed with a concaved cor ner portion as shown in'FigL- 1, but that said corner portion as well as the remainder of the sideof the clay body will be rou hened or.

corrugated to correspond with't e upper 1'0 r brick or clay body produced by the use of this form of bar, will result in the production of a brick such as that shown in Fig. 6 of the drawing. 4

,; While we have shown herein but two forms of shapin and corrugating bars, it will be un-.

derstood t at barsof a similar character havdiflerent outlines for the productionof brick of varying outline, may be used without de arting from the spirit of our invention.

hat we claim, is:

1. An attachment for the discharge end of a brick machine comprising a bar having one of its edges inclined and 1ts underside pro vided with a. projection extending lengthwise of the bar.

2; The combination and its discharging die, of a bar secured in with a brick machine front of-"said discharging die, said bar being shaped to conform to the, shape of the brick to e r wit bead;

In testimony whereof we afiix our signatures in presence of'two witnesses.
